valreindelacroix over on curseforge reports right-clicking an ingredient no longer works and suspects Craftsim.

I've run into that too even without Craftsim.  It comes and goes.  For me, it's been happening on initial load on my first toon.  Then it goes away for the rest of the session.  I'm working on a solution already.  I think Bliz changed something that has affected when their API reliably answer my question "what are the recipes?" and it's reporting "recipes?  none!" because I maybe ask it before its head is screwed on properly. So I'm trying to compensate for the unreliable API for like the 1000th time now.
